In NINJA GAIDEN 3: RAZOR'S EDGE, the enigmatic warrior Ryu Hayabusa must fight to lift a curse that threatens to destroy him. Developed by Team NINJA, the fighting game was designed from the ground up to satisfy core NINJA GAIDEN series fans with a redesigned battle system, improved enemy AI, greatly reduced QTE interactive sequences, and the bloody return of dismemberment. Even with severed arms or legs, enemies will fight on and players will find they have to constantly change up their attacks to win tough battles—the challenge level leaves very little room for error. However, with perfect attacks players can not only cut off limbs but slice an enemy completely in two!
The Ninja Skills systems lets players use Karma earned in battles to purchase weapon and Ninpo upgrades, feats, and costumes to build their own perfect ninja. Adding to the variety of gameplay, Kasumi, Ayane, and Momiji all join Hayabusa as playable characters. Ayane gets her own chapters in story mode while all three female characters can be played in the new Chapter Challenge mode as well as Ninja Trials co-op play.
Chapter Challenge mode has been expanded to include ten chapters (including new Ayane stages) allowing players compete for the highest possible score in each chapter of the story. Six weapons for Hayabusa are included in the game, and the female characters get their own weapons for even more variety. Additionally, Inferno, Wind Blades, and Piercing Void have been added as new Ninpo. In the new Tests of Valor challenges, players discover Crystal Skulls hidden in each level to be transported to engage in tough boss battles.
The online features in NINJA GAIDEN 3: RAZOR'S EDGE have been greatly expanded, including all of the previously paid DLC from NINJA GAIDEN 3. The Ninja Skills upgrade system can be used online letting players use Karma to purchase customizable features for the Unknown Ninja used in multiplayer Clan Battles. Players can use all of game's weapons and Ninpo in Clan Battles, for which five new stages have been added, giving them access to their favorite methods of attack. The number of co-op missions in Ninja Trials mode has been tripled, and all four playable characters are available for this mode.
